SALT LAKE CITY - Do you have the potential to become The Biggest Loser?

The hit NBC show will give Davis County residents the chance to find out for themselves when producers hold an open casting call April 19 from 10 a.m. to 6 p.m. at the KSLTV studios in Salt Lake. This year, the show is looking to cast families of four who want to compete together.

“It’s something we’ve never done before,” said Ned Johnson, a casting associate producer for the show.

The groups can be in any combination, from siblings to in-laws parents and children or aunts and uncles and nieces and nephews. The show is also seeking individuals and former athletes, whether they played in high school, college or professionally.

“With shows like this, they’re looking for people with a great personality and outlook on life,” said Johnson. “The kind of people America would want to spend 50 episodes hanging out with.”

Potential contestants aren’t allowed to line up more than three hours before the opening of the auditions. Still, it’s best to get as close to that mark as possible.

“There will be quite a bit of a line,” said Johnson.

Waiting won’t be boring, however. Representatives from The Biggest Loser Resort in Ivins, Utah will be on hand to give away a week-long stay at the resort to those in line. The resort will also send a trainer to lead those in line through exercise routines.

“They’ll energize contestant hopefuls standing in line,” said Jill Carmen, who does PR for the show. Salt Lake is one of only four audition cities to get either the drawing or the trainer.

All applicants must be at least 100 pounds overweight. They should bring a non-returnable headshot to leave with producers. For more information and to download a contestant application, visit thebiggestlosercasting.com.
